Move over, slowpoke coronavirus tests that take a week or more to return a result — there’s a new generation of rapid tests coming to town and they’re poised to transform the landscape.
They are the antigen tests. But are they really all they’re cracked up to be?
The US Food and Drug Administration granted emergency use authorization to another antigen test this week, bringing the total to four.
Compared to the most commonly used type of coronavirus test in the country — molecular diagnostic tests, also called PCR tests — antigen tests don’t need complicated chemicals, viral transport media or RNA extraction kits. They don’t necessarily require appointments at specialized labs, highly trained technicians, or certain machines.
And they can provide an answer in minutes, rather than hours or days.
